...eer David M. Lynn, a team has developed methods to coat stents with films of nanostructured layers of DNA and cationic polymers. The polymers degrade and DNA is released into the surrounding cells. This approach is similar to current stents coated with small-molecule drugs. "While current stent coatings ...
